An optical illusion is a visual trick that deceives your eyes and brain, making you perceive something completely different from reality. It works by manipulating elements like colours, shapes, light, or patterns in an image, which causes your brain to misinterpret the visual information it receives. This leads to fascinating effects where stationary objects might appear to move, parallel lines might seem to bend, or identical items might look like they vary in size, all because your brain is trying to make sense of intentionally misleading visual cues.
The Image below is a famous drawing which was published for the first time in a German postcard in 1888, and it later became popular due to cartoonist W.E. Hill in 1915. This Image is termed as “My Wife and My Mother-in-Law.” It is a very good example of cognitive illusion in which one image contains two very different faces. The following picture can be viewed in two ways:
First Interpretation: Some viewers might see a young woman glancing over her shoulder.
Second Interpretation: Others may perceive an old woman with a large nose looking downward.
It is all about what your mind wants to see. Take your own time, look closely. What do you see first?

Do you see a young woman with a fancy feather hat, or an old woman with a long nose and fur collar?

Which face did you see first- the young woman or the old one?

Did you find any of them? If yes, then now try to spot the other woman, she’s there! It will take a moment, but both figures coexist within the same lines.
Now here is a small Hint for you so that you can find the other woman too:
If you saw the young woman first :
Look at her chin – it’s the old woman’s nose.
Her ear becomes the old woman’s eye.
Her neck and necklace become the old woman’s mouth and chin.
Now, imagine the old woman is looking down to the left, not away.
If you saw the old woman first:
Her nose becomes the young woman’s chin.
Her eye becomes the young woman’s ear.
Her mouth is the young woman’s necklace and neckline.
Now, imagine the young woman is turning away, looking into the distance.
